He's talking about the fact that Emotiva tried (unnecessarily) to re-invent the way the signal path works when doing bass management: they are applying EQ, distance settings, and several other adjustments before the high-pass crossovers, low-pass crossovers, and summing of low frequency signals with the LFE channel to produce the combined subwoofer signal. It's not the way other manufacturers do it, and it's a bad idea because the distance delays get applied before the steering takes place and because it forces the EQ-ing of the speakers to all address the lowest frequencies (reducing the number of EQ channels available to resolve problems in the lowest octave bands, areas that frequently need a lot of help). It's probably one of the UMC-1's biggest design problems, along with the inability to provide a true video pass-through. The other bugs are certainly problems (issues getting the EQ to operate, problems with audio signal acquisition, HDMI handshaking problems, etc.), but that's one that they've declared to be a design feature - therefore not something they see any reason to "fix." Like mach128, I sincerely hope (and expect) Outlaw to not copy that particular page from Emotiva's playbook.
